Personally identifiable information (PII) is any information that can be used to identify, contact, or locate an individual, such as name, address, phone number, email, social security number, etc1. PII is subject to various laws and regulations that aim to protect the privacy and security of individuals’data1. Organizations that collect, store, process, or transmit PII have a responsibility to safeguard it from unauthorized access, use, disclosure, modification, or destruction1.

One of the best practices for protecting PII is to implement access controls, which are mechanisms that restrict access to PII based on the principle of least privilege2. Access controls ensure that only authorized personnel who have a legitimate need to access PII can do so, and that they can only perform the actions that are necessary for their roles and responsibilities2. Access controls can be implemented at different levels, such as network, system, application, or data level, and can use various methods, such as passwords, tokens, biometrics, encryption, etc2.

If an organization’s shared drive contains PII that can be accessed by all personnel, this poses a high risk of data breach, theft, loss, or misuse, which could result in legal, financial, reputational, or operational consequences for the organization and the individuals whose data is compromised3. Therefore, the most effective risk response is to protect the sensitive information with access controls, such as:

Classify the PII according to its sensitivity and impact level, and assign appropriate labels and permissions to the data files and folders2.

Restrict access to the shared drive to only those personnel who have a valid business reason to access the PII, and grant them the minimum level of access required to perform their tasks2.

Implement strong authentication and authorization mechanisms, such as multifactor authentication, role-based access control, or attribute-based access control, to verify the identity and privileges of the users who access the shared drive2.

Encrypt the PII stored on the shared drive, and use secure protocols and channels to transmit the data over the network2.

Monitor and audit the access and activities on the shared drive, and generate logs and reports to detect and respond to any unauthorized or anomalous events2.

The other options are not as effective as access controls, because they do not directly address the root cause of the risk, which is the lack of access restrictions on the shared drive. Implementing a data loss prevention (DLP) solution, which is a tool that monitors and prevents the leakage of sensitive data, may help to detect and block some unauthorized data transfers, but it does not prevent unauthorized access or viewing of the PII on the shared drive4. Re-communicating the data protection policy, which is a document that defines the rules and responsibilities for handling PII, may help to raise awareness and compliance among the personnel, but it does not enforce or verify the actual implementation of the policy. Implementing a data encryption solution, which is a technique that transforms the PII into an unreadable format, may helpto protect the confidentiality of the data, but it does not prevent unauthorized access or modification of the data, and it may introduce additional complexity and overhead to the data management process.

As strategies evolve, so do the acceptable risk thresholds (tolerances). Regular KRI reassessment ensures alignment with the current risk appetite and supports timely, risk-informed decisions.

A web-based service provider is an organization that offers online services or applications to its customers or users, such as e-commerce, social media, cloud computing, etc. A web-based service provider depends on the availability, reliability, and security of its web servers, networks, and systems to deliver its services or applications.

A low risk appetite for system outages means that the organization is not willing to accept a high level or frequency of system outages, which are interruptions or disruptions in the normal operation or functionality of the web servers, networks, or systems. System outages can cause customer dissatisfaction, revenue loss, reputation damage, or legal liability for the web-based service provider.

A current risk profile for online security is the current state or condition of the online security risks that may affect the web-based service provider’s objectives and operations. It includes the identification, analysis, and evaluation of the online security risks, and the prioritization and response to them based on their significance and urgency.

The most relevant observation to escalate to senior management is an increase in attempted distributed denial of service (DDoS) attacks, which are malicious attacks that aim to overwhelm or overload the web servers, networks, or systems with a large volume or frequency of requests or traffic, and prevent them from responding to legitimate requests or traffic. An increase in attempted DDoS attacks indicates a high likelihood and impact of system outages, and a high level of threat or vulnerability for the web-based service provider’s online security. Escalating this observation to senior management can help them to understand the severity and urgency of the risk, and to decide on the appropriate risk response and allocation of resources.

The other options are not the most relevant observations to escalate to senior management, because they do not indicate a high likelihood or impact of system outages, and they may not be relevant or actionable for senior management.

An increase in attempted website phishing attacks means an increase in malicious attempts to deceive or trick the web-based service provider’s customers or users into providing their personal or financial information, such as usernames, passwords, credit card numbers, etc., by impersonating the web-based service provider’s website or email. An increase in attemptedwebsite phishing attacks indicates a high level of threat or vulnerability for the web-based service provider’s online security, but it may not directly cause system outages, unless thephishing attacks are used to compromise the web servers, networks, or systems. Escalating this observation to senior management may not be the most relevant, because it may not reflect the web-based service provider’s risk appetite for system outages, and it may not require senior management’s involvement or approval.

A decrease in achievement of service level agreements (SLAs) means a decrease in the extent or degree to which the web-based service provider meets or exceeds the agreed or expected standards or criteria for the quality, performance, or availability of its services or applications, as specified in the contracts or agreements with its customers or users. A decrease in achievement of SLAs indicates a low level of customer satisfaction, retention, or loyalty, and a low level of competitiveness or profitability for the web-based service provider. Escalating this observation to senior management may not be the most relevant, because it may not reflect the web-based service provider’s risk appetite for system outages, and it may not require senior management’s involvement or approval.

A decrease in remediated web security vulnerabilities means a decrease in the number or percentage of web security vulnerabilities that have been identified and resolved or mitigated by the web-based service provider. Web security vulnerabilities are weaknesses or flaws in the web servers, networks, or systems that can be exploited by malicious attackers to compromise or damage the web-based service provider’s online security. A decrease in remediated web security vulnerabilities indicates a low level of effectiveness or efficiency for the web-based service provider’s web security controls or processes. Escalating this observation to senior management may not be the most relevant, because it may not reflect the web-based service provider’s risk appetite for system outages, and it may not require senior management’s involvement or approval. References =

The percentage of unpatched DMZ servers is a critical KCI for preventing cyber risk events on external-facing infrastructure. Unpatched servers are vulnerable to exploitation, and monitoring this indicator helps ensure timely application of security updates, reducing the risk of successful attacks.
